What is self-healing infrastructure and why do you need it? The first part is easy; it’s exactly what the name implies. It’s a methodology for creating automation that allows systems to identify and repair errors and misconfigurations without any human action. The “why” is a little more complex, but, like self-healing infrastructure, is well worth the effort.

In a previous blog post, we dove into the wayback machine and looked at Simple Network Management Protocol (SNMP) Traps – a technology that allows devices (including network devices) to send alerts when specific thresholds have been reached. In this post, we are going to be a bit more forward looking and discuss some technologies that will, in theory, replace SNMP. It is important to keep in mind that the demise of SNMP has been predicted for years (actually decades).

Many users are already comfortable with PromQL but need the additional performance and scalability of the VMware Tanzu Observability platform.
